I put on righteousness, and it clothed me (comp. Isaiah 61:10; Psalms 132:9, etc.). Job "put on righteousness;" i.e. made it as the garment wherewith he clothed himself withal (Psalms 109:18, Psalms 109:19), covered up with it all his own natural imperfections, and made it part and parcel of his being.
It was a beautiful covering, and, when once he had put it on, it clung to him, and could not be removed. It "clothed him," or rather, if we translate the Hebrew literally, "clothed itself with him." putting him on, as he had put it on.
It was not merely external; it was internal, a habit of his soul and spirit. My judgment was as a robe and a diadem; rather, my justice (see the Revised Version). My "justice," or "righteousness" (for the words are synonymous), was at once my robe and my crown, my necessary clothing and my ornament.
